Carriage of goods consisting mainly of special ship. Most of its space for storage of cargo hold. Cargo ship, the size disparity, discharge from hundreds of tons to hundreds of thousands of tons of.

Dry bulk cargo ship

Also called bulk carrier, dedicated to the delivery of coal, ore, grain, fertilizer, cement, steel and other bulk materials. At present, its amount is next to tanker. Its characteristic is, the cab and engine room arrangement at the rear hatch, broad; inner bottom and side to side plate connected to tilt, for goods to hold central, deck under two side and hatch with inclined top side tank in order to restrict the movement of goods; there is more water ballast tank for pressure loaded sailing. According to the goods carried by a different, can be divided into ore ship, collier, bulk grain ship, bulk cement carrier transport boats, etc..

Liquid cargo ship

Special carrying liquid cargo ship. Liquid cargo are oil, gas, water and chemical liquid etc.. The volume is the largest petroleum and its products. According to the goods carried by a different, can be divided into raw oil, product oil tanker, chemical tanker, liquefied gas ship.

Crude oil tanker

Special for the transport of crude oil tanker ship, referred to as. As the oil volume is huge, tanker loading capacity is up to about 500000 tons, is the largest ship. Structure general single bottom, with the improvement of environmental requirements, structure is double shell, double bottom form evolution. A stern superstructure. The deck without large hatch, pumps and pipelines in loading and unloading of crude oil. A heating facility at low temperature for heating crude oil, preventing coagulation and impact loading. VLCC draught of up to 25 meters, often can not dock loading and unloading, and must rely on the underwater pipeline for loading and unloading of crude oil.

Product tanker

Specifically, gasoline and other petroleum products carrying diesel ship. Structure and oil tanker tonnage is similar to, but smaller. High fire, explosion-proof requirements.

General cargo ship

Also known as general cargo, general dry cargo ship ship or all goods, mainly used for loading general packaging, bags, boxes and barrels pieces of miscellaneous goods. As a result of miscellaneous goods in smaller quantities, groceries boat tonnage than bulk carriers and tankers for small. Typical cargo volume in about 1~2 million tons, usually double deck, complete with crane equipment. Deck cargo and layered more, is convenient to separate the goods. The new general cargo ship for a variety of uses, both carrying ordinary pieces of groceries, bulk cargo, can also carry bulky cargo, refrigerated cargo and container.

Container ship

Also known as box shipping, container ship or cargo ship, is a kind of special carriage of container ship. All or most of their cabin used for loading container, often in the deck or hatch cover can also be stacked container. Container ship cargo hold hatch long and wide, the size according to requirements of specifications contained in the box. High efficiency of loading and unloading, greatly shortens the port time. In order to obtain a better economy, its speed is generally higher than that of other cargo ship, highest can amount to30 above.

Liquid chemical tanker

Specifically for the transport of toxic, volatile, belongs to dangerous liquid chemicals, such as methanol, sulfuric acid, benzene and other ships. The cargo area for double hull structure, to reduce the risk of spillage when the ship damaged goods. Cargo and crew accommodation spaces, such as drinking and cabin with space isolation. Cargo capacity according to the shipment of dangerous degree to be restricted certainly.

Liquefied gas carrier

Special transport liquefied gas ship. The transport of liquefied gas is liquefied petroleum gas, liquefied natural gas, ammonia, ethylene, chlorine and other. The cargo of the low boiling point, are flammable, explosive goods, some are highly toxic and corrosive. So LNG transport ship cargo complex structure, high cost.

Liquefied gas carrier by liquefied gas storage and divided into three types: pressure, cooled and the cooling type. In the pressure liquefied gas vessel, cargo at room temperature loading in spherical or cylindrical pressure liquid tank. Cold pressing and cooling liquid cargo ship goods in the gas temperature and pressure are controlled, thus requiring liquid tank insulation and cargo cooling device.

Refrigerated ship

Special carrier such as fruit, vegetables, meat and fish to be refrigerated cargo ship. Often a stacked deck, cargo holds are usually separated into several independent closed space. The ship has a high-power refrigerating device, can be in bad environment, so that the refrigerated cargo in keeping the goods required for the appropriate temperature.

Barge carrier

Special carrying cargo ship, also known as mother ship. The means of transportation and container transportation, because the barge is considered able to float on the surface of container. The transport of goods loading process is: first to unified specifications square barge ( son of ship ), the cargo barge loaded on barges ( ship ), the cargo barge barge to the port of destination, the cargo barge unloading to the surface, then distribute the respective destination by tug. Barge carrier is characterized by no terminals and yards, loading and unloading of high efficiency, convenient sea - River transport. But because of high cost, cargo distribution organization is complex, its development has been limited.

Ro

Use of vehicle loading and unloading cargo under multipurpose ship, originally called roll on roll off. Will be equipped with a large cargo containers and trailers loaded with goods as a cargo pallet pulley unit, directly from the tractor or forklift access for loading and unloading cargo. The ship is usually in the aft cargo door and the springboard, the vehicle can be a springboard, the deck cargo door and the activities of inter-ramp or lifting platform, directly into each deck. Therefore, ro-ro ship or pier does not require conventional landing equipment was very high efficiency of loading and unloading.
